Formulation Development

Pre Formulation Studies

Characterization of the Active Pharmaceutical Ingredient (API) is critical for designing a successful formulation approach. DRF can evaluate the characteristics of your active compound, conduct small-scale studies to understand key parameters around solubility and stability, and perform excipient compatibility studies to identify the right ingredients to enhance your APIs performance across a variety of dosage forms. Further, DRF has brought on-board various technologies to control and reduce particle size, which among other things, can greatly enhance the bioavailability of your finished product
